WASHINGTON -LRB- CNN -RRB- -- Most of the Supreme Court justices piled up a lot frequent flyer miles in 2007 , jetting to such exotic locales as Austria , India and Hawaii , according to financial disclosure reports released Friday .

The U.S. Supreme Court justices at a shoot for their 2006 `` class photo . ''

And they generally have a good bit of spending money for their travels , based on reported investment income .

The records , which were released Friday by the Administrative Office of the U.S. Courts , confirm what has been known for some time : that most of the justices are relatively well-off financially .

The eight associate justices make $ 208,100 in annual wages plus income from a variety of resources . Federal judges are not required to publicly release exact income figures , just a general range .

The wealthiest justice may be David Souter , with a wise investment he made years ago in a Vermont bank paying off handsomely . His assets in Chittenden Corp. are valued from $ 5 million to $ 25 million .

Justice Ruth Bader Ginsburg 's asset totals are boosted by the fact that her husband , Martin , is a respected private tax attorney in Washington .

Justices Stephen Breyer , John Paul Stevens and Antonin Scalia are also millionaires . Justice Samuel Alito , the newest member of the high court , also reported income ranging from $ 700,000 to $ 2 million .

In the area of reported gifts , Alito cited about $ 500 in `` Italian food and wine '' given to him by a friend , about whom the justice helpfully noted it `` is not likely that he will appear before this court . ''

The latest financial records continue to show Justices Anthony Kennedy and Clarence Thomas reporting assets under $ 1 million , not including homes and judicial salaries .

Thomas received a one-time boost to his income when his best-selling memoir was released in October . He received the remaining half of a reported million-dollar book advance and traveled extensively on a book promotion and signing tour .

Scalia also received an advance for his book on how to be a better appellate lawyer . The amount was relatively paltry compared to his colleague 's : $ 33,000 .

The annual records show that Breyer , Ginsburg , Kennedy and Scalia were the busiest travelers . Each made multiple visits overseas to teach , give speeches or attend judicial seminars .

Airfare , lodging and meals were generally paid for by the organizations that invited the justices , but under federal law , they must report it .

Europe was a favorite destination for several justices .

Breyer reported 21 out-of-town trips for which he was reimbursed , including to Paris , France ; Rome , Italy ; New Delhi , India ; and Palm Springs , California .

Ginsburg went overseas to France , Belgium , Ireland and Canada and made at least nine other domestic trips .

In the same week in July , Kennedy and Chief Justice Roberts were in France and Austria , respectively .

But the Most Traveled Award goes to Scalia , who made 33 expense-paid trips , including eight overseas , and visited at least 17 states .

Only Souter and Stevens reported no trips for which they were reimbursed by sponsoring groups . Souter also reported no outside teaching gigs , trustee or board memberships , or any gifts received .

The 68-year-old bachelor generally spends his extended time away from the high court at his isolated farm in rural New Hampshire .

Chief Justice John Roberts may have the most diverse investment portfolio . He recorded 63 investments and trusts , including stock in Time Warner -LRB- parent company of CNN -RRB- , Citicorp , Microsoft and Hewlett-Packard .

The estimated value is from about $ 2.4 million to more than $ 6 million .

Before becoming a federal judge , Roberts was a high-paid Washington lawyer . His judicial salary is $ 217,400 .

Roberts , 53 , continued to sell off small amounts of common stock , including in Cisco and Citigroup . When he took over as chief justice in 2005 , he was forced to sell stock in several companies .

A bill passed two years ago in Congress allows federal judges to defer paying capital gains taxes on securities they sell to avoid conflicts of interest . High-level executive branch employees had enjoyed that privilege for years .

The issue of judges holding such diverse investment portfolios has resulted in several conflicts of interest , prompting calls for reform .

The high court last month refused to accept an appeal from a group of South Africans seeking to sue U.S. and foreign firms for allegedly helping keep the white-led apartheid government of their country in power for decades .

Four members of the high court were forced to remove themselves from consideration of the cases . No reason was given for their recusal , but financial disclosure reports showed that Roberts , along with Breyer and Alito , owns stock in several of the companies being sued . Kennedy 's son Gregory is a top manager in one , investment bank Credit Suisse .

Under federal rules , at least six justices must hear a case that is accepted for review . With four of the nine recused , the high court had no choice but to uphold the lower court ruling , tossing out the lawsuit .

Some reform advocates say that judges should be allowed to own only mutual funds instead of individual stocks .

Mutual funds involve a range of investments whose identities are disclosed to the fund 's shareholders several times each year . Federal law allows judges to own mutual funds without having to recuse themselves from a particular appeal .
